Wireless communication device, wireless communication method, center device, and recording medium

Abstract

The invention provides a wireless communication device, a wireless communication method, peripheral equipment and central equipment. Wireless communication is effectively carried out while crosstalk is avoided. The peripheral equipment (200) sends an announcement including a connection priority sequence when the central equipment (100) is connected with the device; the central equipment (100) receives the announcement; the central equipment (100) obtains the connection priority sequence in the received announcement; on the basis of the obtained connection priority sequence, the central equipment (100) controls sending for a connection request signal of the peripheral equipment (200); the peripheral equipment (200) receives the connection request signal sent by the central equipment (100) according to the sent announcement; and the peripheral equipment (200) determines connection with the central equipment (100) according to the connection request signal.

Description

technical field [0001] The present invention relates to a wireless communication device, a wireless communication method, a peripheral, and a central. Background technique [0002] In recent years, Bluetooth (registered trademark) low energy (hereinafter referred to as BLE), which is a short-range wireless communication standard that suppresses power consumption, has become popular. [0003] Wireless communication based on this BLE is performed between a peripheral device as a wireless communication device providing a service and a central device as a wireless communication device utilizing the service. [0004] Specifically, first, the peripheral device intermittently transmits notification information called advertisement (advertisement) for notifying the overview of services it owns and its own existence. Next, when the central device receives the announcement, it sends a connection request signal to the peripheral device. Next, when the peripheral device receives the c...

Problems solved by technology

[0009] However, when a peripheral device sends a notification including a plurality of pieces of identification information, even if the central device to be connected has a priority order, it is not always possible to receive a connection request signal in that priority order.

In addition, in this case, there is a concern that the connection request signals are simultaneously transmitted from a plurality of specific center devices, and crosstalk may occur in the plurality of connection request signals.

[0010] In addition, it is also conceivable that the peripheral device only includes the identification information of the first central device that it wants to connect to, and transmits a predetermined number of notifications, and thereafter, in the case of the second and third cases, it is individually prioritized every predetermined number of times. The method of sending multiple times, but the standby time of the subsequent central equipment will be longer, and the efficiency is poor
